Interactive GIS Map of Benchmarked Buildings

To better visualize the benchmarking data the County receives every year, DEP developed an interactive GIS map that includes covered buildings’ location, property type, size, year built, compliance status, energy metrics, and ENERGY STAR score (if available). Explore all the data filters and search functions to see how commercial buildings in the County are performing. Data are updated annually in October.

Local Benchmarking Ambassadors

DEP is proud to recognize our list of  Benchmarking Ambassadors (Google Doc).  These individuals attended special 3-hour "train-the-trainer" Ambassadors Trainings, taught by EPA ENERGY STAR Portfolio Manager Staff, got the details about complying with Montgomery County's law, and information on accessing data from utilities. If you have a question about the law or how to best proceed with your benchmarking, these individuals and organizations are a great place to start.

Disclaimer: Inclusion in this list does not confer certification, an official endorsement, or approval from the Montgomery County Government or any of its agencies.


DEP’s Building Inventory

DEP developed a preliminary  Covered Buildings Inventory (MS Excel, 116 KB) to raise awareness about the Benchmarking Law. This list was created with current Maryland tax assessment records and the CoStar commercial building database. Please refer to the accompanying  Covered Buildings Inventory informational document ( PDF, 358 KB) which outlines DEP's data sources, assumptions, and definitions used in the inventory.

Note: This inventory is an approximation, meant to raise awareness about the law and help identify the buildings covered by the law.  Each building owner will need to confirm their own building square footage to determine coverage under the Law.


Building Definitions and Scenarios Guide

With the variety of building arrangements, parcels, and complexes in the County, benchmarking your Covered buildings under the Benchmarking Law might have you scratching your head. DEP is here to help! We've put together a document that will walk you through the different scenarios you may find your Covered building in, whether or not you need to benchmark under the Law, and next steps for each scenario.

Tenant Information Request Letter Template

Building owners may need to request operations information from their tenants to have a full and complete Portfolio Manager property entry.This template includes: a table to enter contact information, sample transmittal memo text, required and optional fields for space use types for your tenants to complete, and a utility account information data release form. Using this template is optional--you may collect data from your tenants however you wish, but this template makes it easy to get the information you need quickly! Building owners must request any space data needed in writing to the tenant no later than March 31 of each compliance year. Tenants must respond within 30 days of a request, per the Benchmarking Law. Using this template is not required and is only meant as a guide.  Tenant Information Request Letter Template (MS Word, 99 KB). 


Reported and Disclosed Metrics

The Benchmarking Law requires the County to make reported benchmarking information readily available to the public. Not all collected metrics will be disclosed. The collected but undisclosed data will only be used to provide aggregate metrics and portfolio-wide benchmarks.  DEP Fact Sheet: Metrics Reported and Disclosed ( PDF, 26 KB).


Building Exemption and Waiver Application

Per the Benchmarking Law, commercial buildings may request an exemption for certain use types or a waiver if the building meets certain requirements using the Building Exemption/Waiver Application. Building owners should submit applications for exemptions and waivers to DEP no later than May 1 of each deadline year.
